[X] The Suitcase
Because it's by far the best.
[X] The vambrace unfolds, twisting and widening until it becomes a large kite shield, twisting and rotating until you clench your fist again, and it locks into place. You don't miss the keen edge lining the shield. (Razor Shield, a short-range defensive option with limited offensive capability. Additional Aura bonus.)
Mainly because it's what we need. Transistor's offensive options completely trump any weapon we could carry (yes, even the chainsaw), but the weapon we carry is meant to protect us (or others) whilst the Transistor is unavailable (after using Turn, or if the Transistor is busy doing something else).
As far as the gun option is concerned...we could just carry a gun with us, if need be.

Anyway, this update was pretty interesting. Lumen, in particular, surprised me--I had no idea he basically had to build his personality from scratch every morning. That's horrifying on many levels, really. Also, what the hell happened to Lumen's parents? Why are he and his twin sister living alone with two young children?
Beyond that, it's honestly quite weird, thinking about the team dynamics. On the one hand, it'd be awesome to see Jaune on a team with Ruby and Weiss--because the dynamic between all three of them would be hilarious and heartwarming in all kinds of ways. Jaune would probably see Ruby as a little sister...who has non-stop energy, is absolutely crazy, wields a crazy weapon with absurd effectiveness, and is a huge weapon nut (with all of the engineering expertise that entails). Weiss and Jaune already have a pretty solid and interesting relationship, too.
The canon team would...not work nearly as well, I'd imagine. Jaune would have to overcome his initial...awe and feelings of intimidation by Pyrrah's fame, fighting prowess, and proximity (it would be kind of surreal to go from "that flawless fighter celebrity you've seen a bunch on TV" to "my partner and roommate" literally overnight, while not being on the same team as her puts some distance there, giving him time to adjust and process it all before having to confront it directly). Ren and Nora wouldn't just completely outclass Jaune's skill and standing, so he'd be more immediately coming to grips with their antics and relationship with each other. Which wouldn't be bad, per se, but it'd change the whole tone of it all.
And then you've got this team of OCs that have really grown on us over time. Lumen is somewhat manic, but in a different way from Ruby (he's more of a "fuck everything, I'm 110% done with this shit" manic, while Ruby is "I'm too focused on how fucking awesome this is going to be to worry about how terrifying/dangerous it is"). Creme is relatively sane, normal, and happy, but she's got the specter of the White Fang hanging over her head thanks to her brother. She's kind of a Yang-lite when it comes to teasing, which will be interesting. Ada has half a foot inside the "fight or flight" mentality thanks to the mass murderer after her and the rather lacking support network she's had for all this time. She's often shy, distant, and afraid, which will make things interesting--but she also brings Jaune out of his shell in pretty spectacular fashion, which will be fun.
